The processing device receives a target tire pressure for the tire, receives a current tire pressure of the tire, and controls the operation of the pneumatic pump according to the target tire pressure and the current tire pressure. A method includes receiving a target tire pressure for a tire of a vehicle, receiving a current tire pressure of the tire, and controlling operation of a pneumatic pump according to the target tire pressure and the current tire pressure.

BACKGROUND

Vehicles perform better when the tires are properly inflated.Technicians often check the tire pressure as a courtesy or as part of amaintenance procedure. Vehicle owners sometimes check and fill tires atservice stations or at their homes. The recommended tire pressure isusually indicated on a placard or in the vehicle's owner's manual.Knowing the recommended tire pressure helps the vehicle owner ortechnician properly inflate the tires, especially because differentpressures may be recommended for different types and sizes of tires.

DETAILED DESCRIPTION

An exemplary pump system includes a pneumatic pump, a hose, a nozzlethat can attach to a tire of a vehicle, and a processing device. Theprocessing device receives a target tire pressure for the tire, receivesa current tire pressure of the tire, and controls the operation of thepneumatic pump according to the target tire pressure and the currenttire pressure. An exemplary method includes receiving a target tirepressure for a tire of a vehicle, receiving a current tire pressure ofthe tire, and controlling operation of a pneumatic pump according to thetarget tire pressure and the current tire pressure. The exemplary pumpsystem and method allow a user to fill the vehicle tires with therecommended volume of air.

FIG. 1 illustrates an exemplary pneumatic pump system for fillingvehicle tires to a recommended air pressure. The system may take manydifferent forms and include multiple and/or alternate components andfacilities. While an exemplary system is shown, the exemplary componentsillustrated in the FIGS. are not intended to be limiting. Indeed,additional or alternative components and/or implementations may be used.

As illustrated in FIG. 1, the pump system 100 is configured tocommunicate with and provide air to a vehicle 105. The pump system 100may be configured to communicate directly with the vehicle 105 orthrough a proxy, such as a mobile device 110.

The vehicle 105 may include a passenger compartment 115, tires 120, aplacard 125, a communication module 130, and a vehicle processing device135. The vehicle 105 may include other components than those shownand/or discussed herein.

The passenger compartment 115 may include any area in the vehicle 105configured to receive passengers. The passenger compartment 115 mayinclude seats and controls that allow an operator to control theoperation of the vehicle 105. Example controls may include a steeringwheel, gear shifter, pedals, etc.

The tires 120 may be configured to give the vehicle 105 traction when ona surface such as a road. The tires 120 may rest on a rim 140 and holdair. The tires 120 may be formed from various materials includingsynthetic or natural rubber, fabric and wire, and/or other materials andcompounds. Performance of the vehicle 105 may be optimized when thetires 120 are inflated to a particular pressure, which may be referredto as the target tire pressure. One or more tire pressure monitors 145may be configured to measure the current pressure of each tire 120. Thetire pressure monitors 145 may each output various signals representingthe current pressure, in real time, of a respective tire 120. The tirepressure monitors 145 may further identify which tire 120 is associatedwith the tire pressure monitor 145. That is, the signal generated by thetire pressure monitor 145 may include tire identification code that isunique for each tire. The tire 120 may further include a valve 190configured to receive air from, e.g., an air compressor such as thepneumatic pump 155 discussed below.

The placard 125 may include a card located on or in the vehicle 105 suchas in the passenger compartment 115 or on the inside of a door 150. Insome instances, the placard 125 may be included in an owner's manual.The placard 125 may include information about the vehicle 105 such asthe target tire pressure. Other information included in the placard 125may include the make, model, and year of the vehicle 105, the vehicle105 identification number (VIN), seating capacity, tire 120 size,maximum load, and towing capacity, among other details about the vehicle105. The placard 125 may present the information in any human- and/ormachine-readable format. For instance, the placard 125 may present theinformation as text, a quick response (QR) code, a bar code, an nearfield communication (NFC) tag or other wireless tag, etc. In someinstances, multiple placards 125, including multiple tags, may belocated on or throughout the vehicle such as on or near individual tires120 or wheels. If the tires 120 are replaced, the placard 125 may beupdated or replaced, in whole or in part, to reflect the new target tirepressure if necessary.

The communication module 130 may be configured to allow the vehicle 105to communicate, either wirelessly or through a wired connection, withother devices such as the pump system 100, the mobile device 110, orboth. The communication module 130 may implement any number ofcommunication protocols such as radio frequency (RF), digital shortrange communication (DSRC), and/or Bluetooth®. In some possibleimplementations, the communication module 130 may be configured totransmit signals received from, e.g., the tire pressure monitors 145according to an ultra high frequency (UHF) protocol. The communicationmodule 130 may be further configured to receive signals transmitted fromdevices external to the vehicle 105 and facilitate two-way communicationwith such external devices. For example, the communication module 130may be configured to receive communications from a key fob in a remotekeyless entry system. Moreover, the communication module 130 may beconfigured to receive signals from, e.g., the pump system 100 asdiscussed in greater detail below. In some possible implementations, thecommunication module 130 may be configured to communicate in accordancewith a near field communication (NFC) protocol to communicate with amobile device 110 or any other device implementing NFC standards. Forinstance, when a mobile device 110 taps or is placed near anNFC-compliant tag, which may be included in the placard 125 as mentionedabove, the communication module 130 may transmit and/or receive signalsfrom the mobile device 110.

The vehicle processing device 135 may be configured to receive andprocess various signals generated by components in the vehicle 105. Forinstance, the vehicle processing device 135 may receive and processsignals generated by the tire pressure monitors 145 as well as accessand process information stored in one or more memory devices (notshown). Furthermore, the vehicle processing device 135 may be configuredto store information in one or more of the memory devices. The vehicleprocessing device 135 may further receive and process signals receivedfrom external components such as the pump system 100 and the mobiledevice 110. The vehicle processing device 135 may also transmit signalsto external components using, e.g., the communication module 130. Thus,the vehicle processing device 135 may transmit the current tire pressurefor one or more tires 120 to, e.g., the pump system 100 or the mobiledevice 110.

The mobile device 110 may be configured to communicate with the vehicle105, the pump system 100, or both. The mobile device 110 may beconfigured to receive, process, and transmit signals. In some instances,the mobile device 110 may act as a proxy between the vehicle 105 and thepump system 100. The mobile device 110 may include hardware and softwareto implement any number of communication protocols such as Bluetooth®,near field communication (NFC), or the like. In some possibleapproaches, the mobile device 110 may include and execute one or moreapplications that facilitate the communication with the vehicle 105, thepump system 100, or both. The mobile device 110 may further include acamera configured to capture an image of the placard 125 or otherwiseaccess the information on the placard 125. For instance, the camera ofthe mobile device 110 may capture an image of text, a quick response(QR) code, a bar code, etc. on the placard 125, process the capturedimage, and output a signal representing, for example, the target tirepressure identified on the placard 125. Another possible applicationthat may be executed by the mobile device 110 may include an applicationthat allows the mobile device 110 to access the signals generated by thetire pressure monitors 145. This way, the mobile device 110 may be ableto determine the current tire pressure of any of the tires 120 andtransmit signals with the current tire pressure to, e.g., the pumpsystem 100.

The pump system 100 may include a pneumatic pump 155, a hose 160, anozzle 165, a placard reader 170, a communication device 175, a userinterface device 180, and a pump processing device 185. The pump system100 may not include all of these components in all implementations. Forexample, where the pump system 100 is configured for wirelesscommunication, the pump system 100 may omit the placard reader 170.Including more components, however, may make the pump system 100compatible with a greater number of vehicles 105 since not all vehicles105 may be equipped to communicate wirelessly. The pump system 100 mayinclude additional components such as a device to measure tire pressure(not shown) for instances where communication with the vehicle 105 isnot possible.

The pneumatic pump 155 may include an air compressor configured toincrease the pressure of ambient air and transport the pressurized airthrough the hose 160. The hose 160 may be formed from a generallyflexible material with a skin that is impermeable to air. The pneumaticpump 155 may include a valve (not shown) that allows air to flow fromthe air compressor to an opening in the hose 160. The pneumatic pump 155may push the pressurized air through the hose 160 and through a nozzle165 that is configured to attach to the tire valve 190 so that thepressurized air can enter the tire 120. In some instances, the nozzle165 may be further configured to release air from the tires 120 if,e.g., the tire pressure is higher than the recommended or targetpressure. Thus, the nozzle 165 may include a pressure release valve (notshown) that may be controlled by the pump system 100.

The placard reader 170 may be configured to electronically read theinformation on the placard 125, owner's manual, or any other source ofthe target tire pressure. As discussed above, the placard 125 maypresent information about the vehicle 105 in a human-readable format, amachine-readable format, or both. Thus, the placard reader 170 mayinclude an optical reader or a camera configured to capture images ortext on the placard 125. In some implementations, the placard reader 170may simply capture an image of the vehicle 105. Besides simply capturingimages or text, the placard reader 170 may interpret text through, e.g.,object character recognition or collect information from a quickresponse (QR) code or a bar code. Accordingly, the signal generated bythe placard reader 170 may represent the image captured or alternativelyone or more pieces of collected information, such as the target tirepressure, from the placard 125.

The communication device 175 may be configured to facilitatecommunication between the pump system 100 and other devices includingthe vehicle 105, the mobile device 110, or both. For example, thecommunication device 175 may be configured to receive radio frequency(RF) signals from the vehicle 105 and/or communicate with a mobiledevice 110 via, e.g., Bluetooth® or the NFC protocols. The communicationdevice 175 may be configured to receive signals related to the currenttire pressure, among other characteristics, transmitted from the vehicle105 through the communication module 130 or from the mobile device 110.Accordingly, the communication device 175 may include a wirelessinterface device for wireless communication with the vehicle 105, amobile device interface for wireless communication with the mobiledevice 110, or both. In some possible implementations, the communicationdevice 175 may be further configured to facilitate communication over apacket-switched network such as the Internet. For example, the image ofthe vehicle 105 may be used to determine, from the Internet, the type ofvehicle 105 present and the likely target tire pressure.

The user interface device 180 may be configured to present and/orreceive information. For instance, the user interface device 180 mayinclude an output device, such as a display screen, an input device,such as a keyboard, or both. In some possible approaches, the userinterface device 180 may include a touchscreen display configured toboth present and receive information from a user. The user interfacedevice 180 may implement one or more graphical user interfaces topresent information to the user. In some instances, the user interfacedevice 180, through the graphical user interface, may prompt the user toprovide additional information or to confirm settings such as the valueson the placard 125 received from the vehicle 105 or the mobile device110 through the placard reader 170 or communicated to the pump system100 via the communication device 175. In addition or in the alternative,the user interface device 180 may allow the user to input the targettire pressure manually. Further, the user interface device 180 mayinclude a payment device such as a credit card reader.

The pump processing device 185 may be configured to receive the targettire pressure and the current tire pressure and control the operation ofthe pneumatic pump 155 according to the target and current tirepressures. The pump processing device 185 may receive the target tirepressure via the placard reader 170 or the communication device 175 andthe current tire pressure via the communication device 175. To determinewhich tire 120 is connected to the pneumatic pump 155, the pumpprocessing device 185 may use the identification code broadcast by thetire pressure monitor 145. In addition or in the alternative, the pumpprocessing device 185 may automatically identify the connected tire 120from the current tire pressure that is changing.

Controlling the operation of the pneumatic pump 155 may include enablingthe pneumatic pump 155 when the current tire pressure is less than thetarget tire pressure and disabling the pneumatic pump 155 when thecurrent tire pressure is substantially equal to the target tirepressure. Moreover, controlling the operation of the pneumatic pump 155may include disabling the pneumatic pump 155 and opening the pressurerelease valve to release air from the tire 120 if the current tirepressure is greater than the target tire pressure.

The pump processing device 185 may be further configured to prompt theuser via the user interface device 180 to confirm the target tirepressure received from the placard reader 170, vehicle 105, or mobiledevice 110. The pump processing device 185 may receive the wrong targettire pressure in various situations such as if the placard 125 isoutdated, which may occur if the vehicle 105 no longer has originaltires and the new tires have different pressure recommendations. Thepump processing device 185 may be configured to use the user-providedtarget tire pressure instead of the target tire pressure indicated onthe placard 125.

In some possible implementations, the pump processing device 185 may beconfigured to determine whether calibration of the pneumatic pump 155 isneeded. For instance, the pump processing device 185 may monitor thevolume of air pumped by the pneumatic pump 185 and the volume of airentering the tire 120. If the two values are significantly different,the pump processing device 185 may output a signal to the user interfacedevice 180 indicating that service of the pneumatic pump 155 may beneeded.

The pump processing device 185 may be further configured to processpayment information associated with use of the pump system 100. The pumpprocessing device 185 may receive payment information through, e.g., theuser interface device 180 and associate the target tire pressure withthe payment information or another identifier so that the target tirepressure may be linked to the credit card or other method of paymentused. If the user uses the same credit card during a subsequent trip,the pump processing device 185 may access the previously saved targettire pressure associated with the credit card and prompt the user toconfirm that the target tire pressure is still accurate.

Other possible implementations may allow for the pump processing device185 to associate a particular user and payment information with thevehicle 105. Once the vehicle has been identified from, e.g., theinformation on the placard 125 or a license plate, the pump processingdevice may automatically retrieve the payment information associatedwith the vehicle from a database (not shown) accessible locally or overa communication network.

FIG. 2 is a flowchart of an exemplary process 200 that may beimplemented by one or more components of FIG. 1. For instance, theprocess 200 may be implemented by one or more components of the pumpsystem 100.

At block 205, the communication device 175 may establish a communicationsession with the vehicle 105, the mobile device 110, or both. Thecommunication device 175 may attempt to establish wireless communicationwith the vehicle 105 via, e.g., RF communication or with the mobiledevice 110 through Bluetooth® communication or near field communication(NFC). Establishing communication with the vehicle 105 and/or mobiledevice 110 may include prompting the user, via the user interface device180, to select a vehicle 105 or mobile device 110. Prompting the user tomake such a selection may be helpful if multiple vehicles 105 and/ormobile devices 110 are within a communication range of the pump system100.

At block 210, the pump system 100 may receive information about thevehicle 105. The information may be received at the pump system 100 bythe placard reader 170 or through the communication device 175. In someinstances, the information may be transmitted to the pump system 100directly from the vehicle 105 or through a proxy such as the mobiledevice 110. Additionally or alternatively, the pump system 100 mayreceive information about the vehicle 105 manually from the user throughthe user interface device 180.

At block 215, the pump system 100 may present some or all of theinformation received at block 210 to the user via the user interfacedevice 180. For example, the user interface device 180 may present theuser with the target tire pressure received at block 210. Otherinformation besides the target tire pressure may be presented to theuser as well.

At decision block 220, the pump system 100 may prompt the user toconfirm whether the information presented at block 215 is correct.Instances where incorrect information may be presented at block 215 mayinclude if the pump system 100 is in communication with a differentvehicle 105 or mobile device 110 than the one belonging to the user orif the vehicle 105 has tires with different specifications thanindicated on the placard 125. Knowledge that the installed tires are notthe OEM specified tires may be determined from various vehicle systemsand included in the information transmitted to the communication device175. There may be other circumstances where the user wishes to overridethe target tire pressure so prompting the user to confirm the targettire pressure may give the user the opportunity to input a differenttarget tire pressure than identified on the placard 125. If the targettire pressure is confirmed, the process 200 may continue at block 225.If the target tire pressure is rejected by the user, the process 200 mayreturn to block 210 to attempt to receive the correct target tirepressure or to allow the user the opportunity to manually provide thetarget tire pressure.

At block 225, the pump system 100 may receive the current tire pressurefor one or more tires 120. The pump system 100 may prompt the user toselect which tire 120 the user intends to fill with air, and the pumpsystem 100 may receive the current tire pressure for at least that tire120 from either the vehicle 105 or the mobile device 110. Moreover or inthe alternative, the pump processing device 185 may determine which tire120 is being filled based on the identification codes transmitted by thetire pressure monitors 145 or from whichever current tire pressure valueis changing.

At decision block 230, the pump processing device 185 may determinewhether the current tire pressure received at block 225 is substantiallyequal to the target tire pressure confirmed at block 220. If the currenttire pressure is not substantially equal to the target tire pressure,the process 200 may continue at decision block 235. If the current tirepressure is substantially equal to the target tire pressure, the process200 may continue at block 250.

At decision block 235, the pump processing device 185 may determinewhether the current tire pressure is less than the target tire pressure.If the current tire pressure is not less than the target tire pressure,the pump processing device 185 may conclude that the tire 120 has toomuch air so the process 200 may continue at block 240. If the currenttire pressure is less than the target tire pressure, the process 200 maycontinue at block 255.

At block 240, the pump processing device 185 may disable the pneumaticpump 155 and cause a pressure release valve to open to remove air fromthe tire 120. In some instances, the nozzle 165 may be configured tomechanically open the tire valve 190 when the nozzle 165 is connected tothe tire valve 190 so simply opening the pressure release valve maycause air to escape from the tire 120 without any further interaction bythe pump processing device 185 or other components of the pump system100. In other possible implementations, the pump processing device 185may actively cause a valve in the pump system 100 or the pressurerelease valve to open to allow air to escape from the tire 120.

At block 245, the pump processing device 185 may wait a predeterminedamount of time before returning to block 225. In some instances, thepredetermined amount of time may be in the range of 100 ms to 1 s. Bywaiting and then returning to block 225, the pump processing device 185can monitor the current tire pressure relative to the target tirepressure in real time.

At block 250, the pump processing device 185 may disable the pneumaticpump 155 when the current tire pressure is substantially equal to thetarget tire pressure. Moreover, the pump processing device 185 may closea valve in the pump system 100, such as the pressure release valve, orthe tire valve 190 to prevent a significant volume of air from escapingthe tire 120 after the pneumatic pump 155 has been disabled. In someinstances, the process 200 may end after block 250.

At block 255, the pump processing device 185 may enable the pneumaticpump 155. Enabling the pneumatic pump 155 may cause air to flow into thetire 120 connected to the nozzle 165. While the tire 120 is connected tothe nozzle 165 and the pneumatic pump 155 is enabled, the tire pressureshould increase. The increasing tire pressure may be detected in realtime by one of the tire pressure monitors 145.

At block 260, the pump processing device 185 may wait a predeterminedamount of time before returning to block 225. In some instances, thepredetermined amount of time may be in the range of 100 ms to 1 s. Bywaiting and then returning to block 225, the pump processing device 185can monitor the current tire pressure relative to the target tirepressure in real time.

The process 200 may continue until the current tire pressure issubstantially equal to the target tire pressure. Accordingly, comparingthe target tire pressure to the current tire pressure, the pump system100 may accurately fill one or more tires 120 of the vehicle 105 with aproper volume of air.
